Memorize-It allows you to draw figures but it is not a paint program.  The best way to input a detailed paint style drawing, or clipart, is with cut and paste via the clipboard.  Select the card on which you wish to have a drawing.  Now switch to the paint style program.  Select the desired part of the drawing and then select Edit/Copy.  Now switch back to Memorize-It.  Make sure the current window has the desired card, then select Edit/Paste.  What you selected and copied with the paint program will now be pasted on the card.  You can move and resize it just like any other figure.
